Which country invaded Albania in 1939?

The Italian invasion of Albania (April 7–12, 1939) was a brief military campaign by the Kingdom of Italy against the Albanian Kingdom. The conflict was a result of the imperialist policies of Italian dictator Benito Mussolini. Albania was rapidly overrun, its ruler, King Zog I, forced into exile, and the country made part of the Italian Empire as a separate kingdom in personal union with the Italian crown.

The original Italian plans for the invasion called for up to 50,000 men supported by 51 naval units and 400 airplanes. Ultimately the invasion force grew to 100,000 men supported by 600 airplanes, but only 22,000 took part in the invasion. On April 7 Mussolini's troops, led by General Alfredo Guzzoni, invaded Albania, attacking all Albanian ports simultaneously. The Italian naval forces involved in the invasion consisted of the battleships Giulio Cesare and Conte di Cavour, three heavy cruisers, three light cruisers, nine destroyers, fourteen torpedo boats, one minelayer, ten auxiliary ships and nine transport ships. The ships were divided into four groups, that carried out landings in Vlore, Durres, Sarande and Shengjin.
